valve.
Purge Control Solenoid Valve
Your  Hyundai  is  equipped  with  an
emission  control system  to meet  all
requirements of the Emission prohibi-
tion rules  of your province.
There are three emission control sys-
tems which  are as follows.
The  positive   crankcase   ventilation
system  is  employed  to  prevent  air
pollution  caused  by  blow-by  gases
being  emitted  from   the  crankcase.
This system supplies  fresh air to  the
crankcase through the air intake hose.
Inside  the  crankcase,  the  fresh  air
mixes with blow-by gases, which then
pass through the PCV valve  and into
the induction  system.
The  purge control  solenoid  valve is
controlled by the ECM;  when the en-
gine coolant temperature  is low, and
during idling, it closes, so that evapo-
rated fuel is  not taken into  the surge
tank.  After  engine  warm-up,  during
ordinary  driving,  it  opens  so  as  to
introduce evaporated fuel to the surge
tank.

Control System
In order to assure the proper function
of the emission  control systems, it is
recommended that you have your car
inspected and  maintained by  an au-
thorized Hyundai dealer in accordance
with the maintenance schedule in this
manual.
The exhaust emission control system
is  a  highly   effective  system  which
controls exhaust emission while main-
taining good vehicle  performance.
The  Evaporative   Emission  Control
System  is  designed to  prevent  fuel
vapors from  escaping into the  atmo-
sphere.
Canister
H010E01Y-GAT
EGR System
While the  engine is  inoperative, fuel
vapors generated inside the fuel tank
are absorbed and stored in the canis-
ter. When  the engine is  running, the
fuel vapors  absorbed in  the canister
are drawn  into the  induction system
This  system  helps  control  nitrogen
oxides by  recirculating  a part  of the
exhaust gas into  the engine, thereby
reducing  cylinder   combustion  tem-
perature.
